Cold formed steel member (sometimes called light gauge steel) are made from structural-quality sheet steel that’s formed into shaped either through free-braking blank sheared from sheets or coils,or more commonly,by roll-forming the steel through a series of dies.Unlike hot-formed structural I-Beams,neither process requires heat to from the shape,thus the name”cold formed”steel.Light gauge steel produces are usually thinner,faster to produce,and cost less than their hot-formed counter-parts.
